I compared this with PDFRead (prc-mobi profile), and there are advantages and disadvantages to both. PDFRead isn't as good at turning one portrait-mode page into two landscape-mode pages- sometimes content gets cut off and split across two pages. With a directory of images you don't have to divide each page in two, because the Kindle reader supports panning. On the other hand, the page turns are faster with PDFRead, and I like the fact that it crops out the margins and generates a table of contents automatically.

It's certainly a good solution for me trying to produce a .prc from a .pdf and it's very easy to use.

The only problem I'm having is that the text doesn't look too great. The program seems to make the text very dark and quite grainy when zoomed in. Is this to do with the settings that I've chosen when converting with PDFRead?

Yes, increase the dpi setting to double or even triple what you are using. You probably have a low-resolution .pdf and the dilution gets too pronounced.

Increasing the dpi or setting 'no dilution' will help.

Also, be sure to get the updated NRhtml2mobi.exe mod when creating .prc files. You can even use the Sony MinFilter5 mod as well to increase the resolution of the final output. It's all available at the bottom of post #1 in the PDFRead main thread.

The file I have been left with is attached - as you can see, it doesn't look great when any level of zoom is set.

Thanks,

OK, you're probably not going to like the answer, but due to those crop marks, the margins cannot be removed by PDFRead by itself. It can however, when using unpaper to strip them - see this post on how to do just that; needs experimentation, perhaps on a few pages at a time.

The idea for displaying pdf pages on small screen ebook devices is to somehow gain back those white margins (when using portrait-mode) OR use a landscape profile/mode (see attached screenshot). However, this will require two page turns for each pdf pages. (I told you wouldn't like the answer... )

But there's no other way to increase the clarity/readiblity of the text unless the image can be "zoomed-in" on the ebook page via white margin removal or landscape mode.
